Do you have the trunk carpet secured to the car sheet metal? I would think the sub would just slide and fold up the carpet if you didn't.MKIVSupra said:I used velcro. There is no velcro actually on my trunk carpet, it is just on the sub box and velcroes to the trunk carpet. I wanted to be able to remove my sub box if I needed the room for something.
Did you try velcroing the trunk carpet to the body sheet metal?kebs said:i had the same problem
velcro will not work because it just drags the carpet with the sub it the sub is big.
i also did not want to drill so that idea was gone.
right now i have used 3 of those strap tie-downs attached around the sub and bar on top.
this has worked well so far and i have driven it rather hard.
sometimes you will here it shift because of the slack in the straps but not too much.
only other thing i can think to do is to somehow fabricate brackets to attack it to my amp rack on the back of the seat.
